Ramp metering is the most effective and direct method to control a vehicle entering the freeway. This paper proposed the new density-based ramp metering method. Existing methods that use the flow data had low reliability data and can have various problems. Also, when the ramp metering was operated by freeway congestion, the additional congestion and over-capacity can occur in the ramp. To solve this problem with the existing method, the proposed method used the density and acceleration data of the freeway and considered the ramp status. The developed strategy was tested on Trunk Highway 62 west bound (TH-62 WB) in Minnesota Twin-City and compared with Stratified Zone Metering(SZM), which had been operating in the Twin-City freeway. To constitute the experiment environment, the VISSIM simulator was used. The Traffic Information and Condition Analysis System (TICAS) was developed to control the PTV VISSIM simulator. The experiment condition was set between 2:00 PM and 7:00 PM, Oct 5th, 2014 during severe traffic congestion. The simulation results showed that total travel time was reduced by 20% for SZM. Thus, we solved the problem of ramp congestion and over-capacity.

본 연구의 목적은 최근 미국 내에서 교육 개혁의 한 방편으로 공립학교 학생들에게 교복을 착용하도록 하는 도시가 증가함에 따라 교복 정책에 대한 여론은 찬반론이 교차하고 있고, 이를 뒷받침 할 연구는 부족하여 교복 착용에 관련된 요인들간의 관계를 알아보아 교육정책에 제안하기 위하여 시도되었다. 연구 대상자는 미국 미네소타 주, 도심 지역의 세 남녀 공학 고등학교를 대상으로 조사되었다. 세 고등학교는 학교 의복 착용에 대한 서로 다른 규율을 갖고 있었다. School R은 학교에서 지정한 교복만을 착용 해야 하는 규율을 갖고 있고 School F는 학생들에게 학교가 선정한 색상에 일치하는 의복을 통학복 으로 입을 수 있도록 한 매우 유동적인 교복 정책을 갖고 있었다. School N은 특정한 학교 교복은 없고 학생들에게 통학복 착용에 대한 규율은 있었다. 세 학교의 학부모, 교사, 학생을 대상으로 한 연구 결과는 부모, 교사는 교복 착용이 학생들의 행동에 영향을 미칠 것이라고 인지한 반면 학생들은 전체적으로 그렇지 않다는 태도를 보였다. 학생들에게 선호도가 높은 교복은 School F의 교복처럼 통학복에 색상 제한을 하는 약간은 자유로운 형태로 나타났으며 해당 학교 학생들의 교복에 대한 만족도 또한 높게 나타났다. 교복을 입지 않는 School N의 학부모들은 학생들 통학복에 대한 지출이 다른 두 학교 부모 보다 많은 것으로 나타났다. 또한 교복을 착용한 경험이 오래된 학생일수록 교복 착용에 더 긍정적인 관점을 보인 것으로 보아 미국 내에서의 교복 정책은 초등학교부터 실시하는 것이 바람직한 것으로 받아 들여 진다.

Objectives: The purpose of this study was to analyze the recent research trends in health and mental health literacy and suggest their implications for future research. Methods: Ninety six articles on the topics of health literacy and mental health literacy that were published in journals in Korea during the last 10 years analyzed. Results: The majority of articles were published in medical journals, whereas the articles published in social and natural sciences journals were conducted by multidisciplinary research teams and seemed to be increasing generally. The participants studied in the selected articles were mostly older adults followed by adults aged 18 and over, and other various groups including health professionals and immigrant groups. More than 97% of the articles used quantitative research methods. Conclusions: Health literacy mirrors other health inequalities. To increase the level of understanding of health information, studies should be conducted using various variables. It is also necessary to develop a community education program that can be implemented in the community. Futher, the results highlighted the importance of interdisciplinary research. It is hoped that this effort will help solve t health inequality.

Recently, researches to introduce the performance warranty contract are in progress for quality improvement of road pavements. The performance warranty contract is a type of contract in which contractors guarantee to maintain certain level of performance during a period from completion of construction. The contract use in Europe and the U.S is being increased because it has been known to contribute to improvement of structure quality, reduction of life cycle cost, development of construction techniques, and etc. The research on performance indicators, threshold values, and warranty durations is essential to effectively introduce the contract in Korea. In this study, literatures on the performance warranty contract for concrete pavements of the Minnesota, Indiana, and Florida of the U.S. were reviewed. Major distresses influencing the pavement performance were investigated and analyzed in the jointed concrete pavement sections of 21 Korean expressway routes to be compared to the performance indicators, threshold values, and warranty durations of the states. More accurate comparison is expected by investigation in planned sections for a long time.

The purpose of this research is to compare residents' movement and activities in SH apartment in Yangcheon-Gu, Seoul (SH apartment) and PHA apartment in St. Paul, Minnesota (PHA apartment) in order to improve the quality of rental housing environment. This study had surveyed 418 residents of SH apartments in Korea and used the secondary data gathered from 1,462 residents of PHA apartments in the United States. The results of this study are as follows: The criteria of Korean residents in SH apartments when choosing their residences are lower rent payment and shorter waiting time. They seemed to have no other options than public rental housing. On the contrary, American residents in PHA apartment had more option to choose from. Therefore, Korea needs to offer more variety types of residents that can be lead to better satisfaction of low income classes. Most of the SH apartments residents has lived for long-term, in the average of more than 6 years, and wanted to live continually at their current dwelling. PHA residents showed similar tendency. However, long term residency may lead to permanent occupation of the public rental apartment by the same family. Hence, a system which can provide equal residency opportunities to all low-income classes need to be developed. Residents of SH apartment were satisfied with the personal activities but were not satisfied with group activities among residents or regarding resident meetings. However, residents of PHA apartments were more satisfied with their management because there is more in-housing-complex activity programs. Therefore, more activity program for a resident should be developed after analysing programs of different apartments and current conditions in Korea. There were some noticeable divergences among residents, based on their age, term of residence and physical, emotional and mental problem, when evaluating in-housing-complex's programs. Thus, these factors are also need to be considered when planning and examining evaluation about the management of rental apartments.

Objectives : In this study, we aimed to elucidate the demographic and psychological characteristics of maladaptive soldiers in the Republic of Korean Army. Methods : Study participants included 110 male conscripts who had participated in the Green camp, which was a form of group psychosocial treatment program for maladaptive soldiers. All participants were interviewed and diagnosed by a psychiatrist, and classified into two groups according to whether they left or rejoined the army. We analyzed the differences between these two groups in terms of demographic features, psychiatric diagnosis and the Minnesota Multiphasic Personality Inventory (MMPI) subscores. Results : Compared with soldiers who rejoined their units, those who left military service exhibited significantly lower educational level (p=0.041) and a higher rate in psychiatric treatment prior to enlistment (p=0.011). Among the 106 subjects, 63 (59.4%) and 23 (21.7%) were diagnosed with personality disorder and adjustment disorder, respectively. Further, those who left military service were diagnosed more frequently with mood disorder (p=0.001) and schizophrenia (p=0.014) than those who rejoined their units. Additionally, the MMPI scores of soldiers who left military service were significantly higher on the psychasthenia (p=0.028) and schizophrenia (p=0.039) scales than those of soldiers who rejoined their units. Conclusion : Most of the maladaptive soldiers were diagnosed with mental disorders. The results of this study suggest that systematic, consistent psychiatric evaluation and intervention for maladaptive male conscripts is crucial in the Republic of Korean army.
